HARMON 0. NELSON, OF WHITINSVILLE MASSACHUSETTS, ASSIGNOR T0 WHITIN MACHINE WORKS, OF WHITINSVIIILE, MASSACHUSETTS, A CORPORATION OF MASSA JOURNAL-BEARING.

Application filed December 4, 1916. SeriaI N 0. 134,839.

To all whom it may concern: 7

Be it known that I, HARMON O. N ELSON, a citizen of the United States, residing at Whitinsville, in the county of Worcester and Commonwealth of Massachusettts, have invented certain new and useful Improvements in Journal-Bearings, of which the following is a specification.

y invention relates to spinning, twisting, winding and similar machines Which use idler the bands driving the spindles, and has for its object to provide improved means for retaining the journal-bearings of the idler pulleys in their holders whlle in use, but permit their easy removal whenever so desired. This object I accomplish in the manner hereinafter set forth, reference being had to the accompanying drawings.

Figure 1 of the drawings is a perspective view of an idler pulley hanger showing one of the journal-bearing retaining caps in its normal position and the other open. Fig. 2,

a sectional view taken on line AB in Fig. 1

and Fi 3 is a perspective view of the journal bearing.

Referring to the drawings, 1 designates an idler pulley hanger such as commonly used on spinning and twisting machines. The opposite legs of the hanger are provided with the pockets 2 which hold the bearings 3 for the journals 4: of the idler pulley 5..

The pockets 2 are preferably rectangular in shape, open on theetop and inner side of hanger and closed on the other sides. The journal-bearings are loosely fitted in the pockets so that they maybe easily inserted or removed. Each. bearing is securely held in position in'its pocket by a retaining cap 6 secured to the top of the Copies of this patent may b'e obtained for five cents each, by addressing the Commissioner of Patents,

pocket by the screw 7 tapped into the lug 8 on the outside of the pockets; The cap is prevented from swinging on its holding screw by the depressed portion 9 engaging with the groovelO in the top of the j ournalbearing. By loosening the screws 7 just sufficiently to disengage the caps from the grooves in the bearings and then swinging the caps about their screws, tofully open up the top of the pockets, the pulley and its bearings may be easily removed.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details ofconstruction, set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

I claim:

l. The combination of an idler pulley supported by journals, bearings in which the journals revolve, a hanger comprisin legs each containing a pocket holding a journal-bearing, a retaining cap for holding each bearing in its pocket, said cap being provided with a depressed part for engagement with a groove intop of bearing and'a screw for securlng'the cap on the top of the pocket.

2. A retaining device for a j ournal-bearing comprising a journal-bearing member provided with a longitudinal groove in the top thereof and a retaining cap having a depressed part for 'engag ment with said groove. v

In testimony whereof, I have signed this specification. p 'HABMON O. NELSON.
